(4) I-polyacrylonitrile ye-Hydrolyzed: Ukukhethwa kwe-polyacrylonitrile ye-hydrolyzed kufuneka ibe ngumgubo owomileyo, i-anionic, i-molecular weight 100,000-200,000, kunye ne-degree of hydrolysis 55-65%.
(5) I-Soda ash (Na2CO3): Decalcify bentonite ukuphucula ukusebenza kwayo (6) I-Potassium humate: I-powder emnyama i-20-100 mesh iyona nto ibhetele.
2. Ukulungiselela kunye nokusetyenziswa
(1) Izithako ezisisiseko kudaka ngalunye cubic: 1. Bentonite: 5% -8%, 50-80kg.2. Uthuthu lwesoda (NaCO3): 3% ukuya kwi-5% yomthamo womhlaba, 1.5 ukuya kwi-4kg yesoda ash.3. Hydrolyzed polyacrylamide: 0.015% ukuya 0.03%, 0.15 ukuba 0.3kg.4. Hydrolyzed polyacrylonitrile powder dry: 0.2% ukuya ku-0.5%, 2 ukuya ku-5kg ye-hydrolyzed polyacrylonitrile powder owomileyo.
Ukongeza, ngokwemiqathango yokubunjwa, yongeza i-0.5 ukuya kwi-3 kg ye-agent anti-slumping, i-agent ye-pluging kunye ne-agent yokunciphisa i-fluid yokunciphisa i-cubic meter yodaka.Ukuba ukubunjwa kwe-Quaternary kulula ukuwa kunye nokwandisa, yongeza malunga ne-1% ye-anti-collapse agent kunye ne-1% ye-potassium humate.
(2) Inkqubo yokulungiselela: Phantsi kweemeko eziqhelekileyo, malunga ne-50m3 yodaka iyafuneka ukugrumba umngxuma otsala amanzi oyi-1000m.Ukuthatha ukulungiswa kodaka lwe-20m3 njengomzekelo, inkqubo yokulungiselela "udaka lwepolymer oluphindwe kabini" luhamba ngolu hlobo lulandelayo:
1. Galela i-30-80kg yesoda ash (NaCO3) kwi-4m3 yamanzi kwaye udibanise kakuhle, uze udibanise i-1000-1600kg ye-bentonite, udibanise kakuhle, kwaye ufuke ngaphezu kweentsuku ezimbini phambi kokuba uyisebenzise.2. Phambi kokusetyenziswa, yongeza udaka olufakwe emanzini acocekileyo ukuze ulunyibilikise ukwenza isiseko se-20m3 eludaka.3. Nciba i-3-6kg ye-hydrolyzed polyacrylamide yomgubo owomileyo ngamanzi kwaye uyifake kwisiseko sodaka;nciphisa kwaye unyibilikise i-40-100kg ye-hydrolyzed polyacrylonitrile yomgubo owomileyo ngamanzi kwaye wongeze kwisiseko sodaka.4. Gxuma kakuhle emva kokufaka zonke izithako
(3) Uvavanyo lokusebenza Iipropati ezahlukeneyo zodaka kufuneka zivavanywe kwaye zihlolwe ngaphambi kokusetyenziswa, kwaye ipharamitha nganye kufuneka ihlangabezane nale migangatho ilandelayo: umxholo wesigaba esiqinileyo: ngaphantsi kwe-4% ubunzima obuthile (r): ngaphantsi kwe-1.06 i-funnel viscosity (T) : Imizuzwana eyi-17 ukuya kwengama-21 Umthamo wamanzi (B): ngaphantsi kwe-15ml/30 imizuzu Ikeyiki yodaka (K):
Izithako zokomba udaka ngekhilomitha

Udaka oludityanisiweyo olusezantsi oluqinileyo oluchasene nokudilika
1. Iimpawu
1. Ulwelo olulungileyo kunye nobuchule obunamandla bokuthwala umgubo welitye.2. Unyango olulula lodaka, ukugcinwa kakuhle, ukusebenza okuzinzile kunye nobomi benkonzo ende.3. Ukusetyenziswa okubanzi, akunakusetyenziswa kuphela kwi-strata evulekileyo, ephukileyo kunye neyophukileyo, kodwa nakwi-rock stratum enodaka kunye ne-rock stratum evakalelwa ngamanzi.Iyakwazi ukuhlangabezana neemfuno zokukhusela eludongeni lweendlela ezahlukeneyo zamatye.
4. Kulula ukuyilungisa, ngaphandle kokufudumeza okanye ukucwina kwangaphambili, vele udibanise i-slurries yesigaba esisezantsi esincinci kwaye udibanise kakuhle.5. Olu hlobo lodaka lwe-compound anti-slump alunayo nje umsebenzi wokuchasana ne-slump, kodwa lunomsebenzi we-anti-slump.
2. Ukulungiswa kodaka oluphantsi oluqinileyo oluchasene ne-slump Ulwelo: i-polyacrylamide (PAM) ─potassium chloride (KCl) i-low-solid anti-slump mud 1. Bentonite 20%.2. Uthuthu lwesoda (Na2CO3) 0.5%.3. I-sodium carboxypotassium cellulose (Na-CMC) 0.4%.4. I-Polyacrylamide (i-PAM ubunzima be-molecular yi-12 yezigidi zeeyunithi) 0.1%.5. I-potassium chloride (KCl) 1%.Ulwelo B: I-Potassium humate (KHm) isigaba esisezantsi esiqinileyo sodaka oluchasene nokudilika
1. Bentonite 3%.2. Uthuthu lwesoda (Na2CO3) 0.5%.3. I-Potassium humate (KHm) 2.0% ukuya kwi-3.0%.4. I-Polyacrylamide (i-PAM ubunzima be-molecular yi-12 yezigidi zeeyunithi) 0.1%.Xa usebenzisa, xuba ulwelo olulungisiweyo A kunye nolwelo B kwi-volume ratio ye-1: 1 kwaye ugxobhoze ngokucokisekileyo.
3. Uhlahlelo lweMechanism yeComposite Low Solids Anti-slump yoKhuseleko lweNdonga yodaka
I-Liquid A yi-polyacrylamide (PAM) -i-potassium chloride (i-KCl) i-low-solid anti-slump mud, eludaka oluphezulu olunomgangatho ophezulu wokuchasana nokusebenza kakuhle.Umphumo odibeneyo we-PAM kunye ne-KCl unokuthintela ngokufanelekileyo ukwandiswa kwe-hydration yokwakheka kwamanzi, kwaye inefuthe elihle kakhulu lokukhusela ekuqhubeni kwi-drilling kwi-formations-sensitive formations.Ithintela ngokufanelekileyo ukwandiswa kwe-hydration yolu hlobo lokubunjwa kwamatye ngexesha lokuqala xa ukubunjwa kwamanzi kubonakaliswe, oko kuthintela ukuwa kodonga lomngxuma.
I-Liquid B yi-potassium humate (KHm) i-low-solid anti-slump mud, eludaka oluphezulu olunomgangatho wokuchasana nokusebenza kakuhle.I-KHm yi-ejenti yokunyanga udaka oluphezulu, olunemisebenzi yokunciphisa ukulahleka kwamanzi, ukuhlanjululwa kunye nokusabalalisa, ukuthintela ukudilika kodonga lomngxuma, kunye nokunciphisa kunye nokuthintela ukunyuswa kodaka kwizixhobo zokugaya.
Okokuqala, ngexesha lenkqubo yokujikeleza kwe-potassium humate (KHm) isigaba esisezantsi-solid anti-collapse udaka emngxunyeni, ngokujikeleza ngesantya esiphezulu sombhobho wokubhobhoza emngxunyeni, i-potassium humate kunye nodongwe eludakeni luyakwazi ukukhupha. kulwakhiwo olukhululekileyo noluqhekekileyo phantsi kwentshukumo ye-centrifugal force.I-rock strata ekhululekile kunye neyophukileyo idlala indima yokuqinisa kunye nokuqinisa, kwaye ikhusela umswakama ukuba ungangeni kwaye ucwilise udonga lomngxuma kwindawo yokuqala.Okwesibini, apho kukho izikhewu kunye nokudandatheka eludongeni lomngxuma, udongwe kunye ne-KHm eludakeni luya kuzaliswa kwizithuba kunye noxinzelelo phantsi kwesenzo samandla e-centrifugal, kwaye ke udonga lomngxuma luya kuqiniswa kwaye lulungiswe.Ekugqibeleni, i-potassium humate (KHm) i-low-solid phase anti-collapse udaka ijikeleza emngxunyeni ixesha elithile, kwaye ngokuthe ngcembe inokwenza ulusu oluncinci, oluqinileyo, oluxineneyo kunye nolugudileyo eludongeni lomngxuma, oluthintela ngakumbi. kuthintela ukubola kunye nokuguguleka kwamanzi kwindonga ye-pore, kwaye ngexesha elifanayo lidlala indima yokuqinisa udonga lwama-pore.Ulusu oluludaka oluludaka lunomphumo wokunciphisa ukudonsa kwi-drill, ukuthintela umonakalo womatshini kwindonga yomngxuma obangelwa ukunyakaza kwesixhobo sokugaya ngenxa yokuchasana ngokugqithisileyo.
Xa ulwelo A kunye nolwelo B zidityanisiwe kwinkqubo yodaka efanayo kumlinganiselo womthamo we-1:1, ulwelo A lunokunqanda ukwanda kolwelo “lwesakhiwo sodaka olwaphukileyo” ekwakhiweni kwamatye okokuqala, kwaye ulwelo B lunokusetyenziswa okokuqala Idlala indima kwi-dialysis kunye ne-cementation "ekhululekile kunye neyophukileyo" yokwakheka kwamatye.Njengoko ulwelo oluxutyiweyo lujikeleza emngxunyeni ixesha elide, ulwelo B luya kwenza ngokuthe ngcembe ulusu lodaka kulo lonke icandelo lomngxuma, ngaloo ndlela ludlala ngokuthe ngcembe indima ephambili yokukhusela udonga nokuthintela ukuwa.
